Description

  The present invention relates to a vehicle occupant protection device, and more particularly to a vehicle occupant protection device that protects an occupant seated on a seat device from an impact input from the vehicle width direction outside the vehicle.

  Conventionally, an impact is applied to an occupant seated in a seat device disposed in a vehicle interior adjacent to a side door disposed on a side surface of a vehicle from a vehicle lateral direction (vehicle side), In other words, as a technology for protecting against impacts caused by side collisions (side collisions), an impact bar extending in the vehicle front-rear direction is disposed in the side door body composed of the outer panel and the inner panel, so Technology that suppresses movement into the passenger compartment, and technology that mitigates the impact applied to the occupant during a side impact by accommodating a shock absorbing material (EA material) made of resin foam or the like inside the side door Etc. are known.

  On the other hand, a storage portion (that is, a door pocket) having a space for storing an article such as a map is generally provided on the side of the side door. This storage unit needs to have an empty storage space for the function of storing articles, and therefore there is a problem that the storage unit cannot be used as an impact absorbing region in a side collision. .

  The problem is that the storage space of the storage part is located on the inner side of the side door with respect to the surface of the side door on the vehicle interior side (that is, the storage part is recessed in the side door) or located on the outer side. It is a problem that occurs regardless of whether the storage part is protruding from the side door. In particular, when the storage part is formed to be recessed, the part is impacted on the inside of the side door. The problem that the space for accommodating the absorbent material is eliminated or reduced is also caused. As a result, when a side collision occurs at the position where the storage portion is disposed, that portion of the side door easily moves into the vehicle interior. In addition, since the storage space of the storage unit is often located in the vicinity of the occupant seated on the seat device, when the side door moves into the passenger compartment during a side collision, the storage unit comes into contact with the waist or lower limbs of the occupant. The possibility increases.

  Therefore, it is conceivable to eliminate the storage section and store a sufficient amount of shock absorbing material in the side door located near the lower back and lower limbs of the occupant seated in the seat device. Space is reduced, which is not preferable from the standpoint of vehicle merchandise.

  As a technique for coping with this, Patent Document 1 discloses a structure in which the storage unit can be retracted by, for example, turning or sliding movement from the side position of the waist of the occupant seated on the seat device. A technique is disclosed in which a side door is provided with an airbag that deploys to a position where the storage portion is located while being pushed away. According to this, when the side door moves into the vehicle compartment at the time of a side collision, not the storage portion but the airbag contacts the occupant's waist and lower limbs to protect the occupant.

JP-A-6-16104 (paragraphs 0019 and 0026)

  However, in the above technique, the storage part cannot be formed integrally with, for example, a door trim, and the structure of the side door becomes complicated, and if the storage part turns or slides, the storage part is smooth. There are a problem that the airbag is not retracted and a problem that it takes time to deploy the airbag as the airbag pushes the storage portion.

  Therefore, the present invention leaves the storage part fixed to the side door to secure a storage space around the occupant, and at the time of a side collision, the storage part is converted into an impact absorption area and the occupant seated in the seat device The challenge is to contribute to protection.

It has a length.

  In the cover member 11d, a portion between the operation levers 11e and 11f protrudes to the side door side and constitutes a contact portion 11h. This will be described in detail later.

  Next, as shown in FIG. 4, the side edge of the floor F is coupled to the side sill 19, and the side door 10 in a closed state is positioned above the side sill 19. The side door 10 has an outer panel 31 and an inner panel 32, and an impact bar 34 extending in the vehicle front-rear direction is disposed in a side door main body 33 constituted by both panels 31 and 32. The movement of the side door 10 into the passenger compartment is suppressed. Further, an impact absorbing material 35 made of a resin foam or the like is accommodated inside the side door 10 so as to alleviate the impact applied to the occupant A at the time of a side collision.

  A groove 37 for inserting the window glass 36 is formed at the upper edge of the side door 10.

  As shown in FIG. 5, a door trim 38, which is a resin molded product, is coupled to the side of the side door body 33 with respect to the passenger compartment. The storage portion 13, the armrest 16, and the like are formed integrally with the door trim 38.

  A non-actuated airbag device 20 is provided below the storage space 12 of the storage unit 13. As shown in FIG. 6A, the airbag device 20 includes an inflator 21, an airbag 22, and a box-shaped case 23 that stores the airbag 22. As shown in FIG. 6B, a thin groove is formed on one surface of the case 23 to form a fragile portion 24. At the time of operation, as shown in FIG. 6C, the case 23 is broken at the weakened portion 24, and the airbag 22 is deployed from the broken surface.

  As shown in the enlarged circle of FIG. 4, in the present embodiment, the airbag device in a non-operating state is provided below the side door wall portion 50 constituting the bottom wall of the storage portion 13 with the fragile portion 24 facing upward. 20 is arranged. The airbag device 20 is assembled to the door trim 38. Here, the side door wall 50 is one of a plurality of side door walls that partitions the storage space 12 and the internal space of the side door 10. Therefore, the airbag device 20 is disposed on the inner space side of the side door 10 with respect to the side door wall portion 50 when not in operation.

  Furthermore, as shown in the enlarged circle of FIG. 4, a thin groove is formed in the center portion in the width direction of the side door wall portion 50 to form a fragile portion 41. Further, as shown in the enlarged circle of FIG. 5, thin grooves are also formed on both side portions of the partition wall 13a of the storage portion 13 that partitions the storage space 12 and the vehicle interior space of the storage portion 13, and the fragile portions 42, 42 (see FIG. 2). Further, as clearly shown in FIG. 4, the lower surface 16 a of the armrest 16 is a curved surface that smoothly inclines toward the seat device 11 from the lower side to the upper side.

  Next, the operation of this embodiment will be described.

  When an impact is input to the vehicle 1 from the outside in the vehicle width direction, the impact is detected by a detection device (not shown), the airbag device 20 is activated, the airbag 22 starts to inflate, and the case 23 is It breaks at the fragile portion 24 and begins to expand upward. The airbag 22 breaks the side door wall portion 50 constituting the bottom wall of the storage portion 13 at the weakened portion 41, and enters the storage space 12 of the storage portion 13 from below as shown in FIG. Deployment begins in space 12.

  As the deployment proceeds, the airbag 22 exits from the opening 15 of the storage portion 13 to the vehicle interior space and further expands upward as shown in FIG. Then, along the curved surface of the lower surface 16a of the armrest 16, the development direction is changed to the lateral direction and guided to the seat device 11 side. As a result, the airbag 22 that has exited the storage space 12 from the opening 15 is deployed toward the waist of the occupant A seated on the seat device 11.

  Further, the airbag 22 breaks the partition wall 13a that partitions the storage space 12 and the vehicle interior space of the storage portion 13 at the weakened portions 42 and 42 while being deployed in the storage space 12, and the above-described FIG. 7 and FIG. In addition, as shown in FIG. 9, the upper portion of the partition wall 13 a is displaced toward the seat device 11 as the airbag 22 is deployed. The displaced partition wall 13a abuts against an abutting portion 11h provided on the side portion of the sheet apparatus 11, whereby the displacement is restricted to a predetermined position. As a result, the airbag 22 being deployed in the storage space 12 is deployed toward the waist of the occupant A seated on the seat device 11.

  Thus, in the present embodiment, the storage space 12 of the storage portion 13 provided on the side of the vehicle interior of the side door 10 is the seat device disposed in the vehicle interior adjacent to the side door 10 in the vehicle width direction. 11 is located in the vicinity of the occupant A seated on the vehicle 11. The airbag 22 of the airbag device 20 provided for protecting the passenger A seated on the seat device 11 from an impact input from the vehicle width direction outside the vehicle is configured to store the storage portion at the time of operation, that is, side impact. It expands in 13 storage spaces 12. Therefore, at the time of a side collision, the storage portion 13 is in a state similar to the state in which the shock absorbing material 35 is stored in the storage space 12, and the storage portion 13 is converted into a shock absorbing region. As a result, even if the side door 10 moves into the passenger compartment at the time of a side collision and the storage portion 13 contacts the occupant A seated on the seat device 11, the storage portion 13 contributes to the protection of the occupant A.

  Further, since the airbag 22 is not deployed in the storage space 12 of the storage portion 13 except during operation, the storage space 12 is vacant during normal times other than during operation. Can be secured to the side door 10 to secure a storage space around the occupant A.

  In this case, when the airbag 22 is activated, the side door wall portion (in this embodiment, the side door wall portion constituting the bottom wall of the storage portion 13) 50 that defines the storage space 12 is broken to form a side wall. Since the airbag 10 is deployed from the inside of the door 10 into the storage space 12, the airbag 22 is reliably deployed into the storage space 12.

  In addition, the airbag 22 is not only deployed in the storage space 12 of the storage portion 13 during operation, but is also introduced into the vehicle interior space from the opening 15 of the storage portion 13 facing upward at a position lower than the seating surface of the seat device 11. Since the air bag 22 deployed toward the lumbar region of the occupant A is also deployed toward the lumbar region of the occupant A who is seated on the seat device 11, the lumbar region of the occupant A can be particularly protected at the same time.

  In that case, a direction changing portion (downward) that guides the airbag 22 that has come out of the opening 15 into the vehicle interior space to the seat device 11 side on the lower surface 16a of the armrest 16 disposed above the opening 15 of the storage portion 13. A curved surface that is smoothly inclined toward the seat device 11 from the upper side to the upper side, so that the airbag 22 can be reliably deployed toward the seat device 11 and further toward the occupant A waist. Become.

  On the other hand, a guide unit (a partition whose upper part is displaceable toward the seat device 11 side) guides the airbag 22 being deployed in the storage space 12 toward the waist of the occupant A seated on the seat device 11. Since the wall 13a) is provided, the airbag 22 is deployed toward the occupant A waist part relatively early, and the protection of the occupant A waist part by the airbag 22 is reliably achieved from the early stage. The

  In this case, the guide portion is configured by the upper portion of the partition wall 13a of the storage portion 13 that partitions the storage space 12 and the vehicle interior space being displaced toward the seat device 11 as the airbag 22 is deployed. Therefore, deployment of the airbag 22 toward the occupant A waist is reliably achieved with a simple configuration, and the upper portion of the partition wall 13a is not displaced toward the seat device 11 in a normal state. Thus, an operation space is secured for the operation lever 11e of the seat reclining mechanism and the operation lever 11f of the seat vertical position adjustment mechanism, which are disposed below the side portion of the seat 11.

  In addition, since the partition wall 13a is provided with weak portions 42, 42 so that the partition wall 13a can be displaced, the partition wall 13a breaks at the weak portions 42, 42, so that the partition wall 13a The upper part is reliably displaced toward the sheet device 11 side.

  In this case, since the displaced partition wall 13a abuts against the abutting portion 11h provided on the side portion of the seat device 11, the displacement is regulated at a predetermined position. A Guided toward the waist.

  In addition, in the present embodiment, the storage space 12 of the storage portion 13 is located on the inner side of the side door 10 with respect to the surface 14 on the vehicle interior side of the side door 10, that is, the storage portion 13 is located on the side door 10. Therefore, even when the space between the seat device 11 and the side door 10 cannot be secured, the storage portion 13 is not protruded from the surface 14 on the vehicle interior side of the side door 10 into the vehicle interior space. Can be provided. In this case, even if there is a problem that the space for storing the shock absorbing material 35 is eliminated or reduced in the inside of the side door 10, the storage portion 13 becomes a shock absorbing region at the time of a side collision. Protection and the convenience of securing storage space.

  Next, a second embodiment of the present invention will be described with reference to FIGS. 10 to 14 corresponding to FIGS. 4, 5, and 7 to 9, respectively. Components that are the same as or similar to those in the first embodiment are denoted by the same reference numerals, and only characteristic portions will be described.

  In the second embodiment, unlike the first embodiment, the airbag 22 is a vertical portion of the storage portion 13 among the plurality of side door wall portions that partition the storage space 12 and the internal space of the side door 10. The vertical wall portion 51 outside the vehicle width direction that forms the side wall is broken and deployed in the storage space 12 (see FIG. 12). Therefore, the airbag apparatus 20 is arrange | positioned at the internal space side of the side door 10 with respect to the said vehicle exterior vertical wall part 51 at the time of non-operation (refer FIG. 10). The airbag device 20 is assembled to the inner panel 32. In that case, the airbag device 20 has the surface of the case 23 (see FIG. 6B) on which the fragile portion 24 is formed opposed to the vehicle outer vertical wall portion 51.

  As shown in enlarged views in FIGS. 10 and 11, four thin grooves are formed in the vehicle exterior vertical wall portion 51 so as to draw a quadrangle, thereby forming weakened portions 43. In that case, the weak part 43 located in the lower part is thicker than the other weak parts 43... 43 (see the enlarged circle in FIG. 10).

  According to this, when the airbag 22 is activated, the longitudinal wall portion 51 outside the vehicle width direction is broken at the fragile portions 43... 43 and deployed in the storage space 12. The direction is the horizontal direction (see FIG. 12: in the first embodiment, the direction is vertical from the beginning). As a result, when an article 52 such as a map is stored in the storage unit 13, the article 52 is pressed against the partition wall 13 a of the storage unit 13 and then the side of the sheet device 11 by the airbag 22 ( 13 and FIG. 14), the problem that the article 52 scatters and contacts the occupant A is avoided.

  The airbag 22 is then deployed in the storage space 12 from below to above, and the deployment direction is changed to the lateral direction along the curved surface of the lower surface 16a of the armrest 16, and is guided to the seat device 11 side. Then, it unfolds toward the occupant A's waist (see FIGS. 12 and 13). In that case, the vertical wall portion 51 is broken so that the upper portion is opened so that the expansion from the lower side to the upper side in the storage space 12 is reliably performed. For this reason, the fragile portion 43 located in the lower portion is made thicker than the other fragile portions 43.
